EVIDENCE NEEDED

I can appreciate Mr. Adams concerns and his logic. But I must say I
don't know what the relationship is between smoking cannabis lightly
or moderately and disease in comparison to smoking tobacco. (There
certainly doesn't seem to be a lot of evidence of morbidity rates
related directly to cannabis use at this level.)

We have heard that cannabis contains more "possibly" harmful
substances than tobacco however there doesn't seem to be any official
evidence showing that cannabis is any more - or rather has been more
- - dangerous over say the last 30 to 40 years than tobacco.

Surely there must be some published scientific study or survey of
medical records to provide concrete proof of this theory. Perhaps one
of your readers could enlighten me or direct me to the source of the
evidence.
